Climate change remains a critical subject of global interest, defined by long‑term shifts in weather  patterns and rising temperatures. Although natural events like volcanic eruptions once shaped these changes, human activities, especially fossil‑fuel burning, deforestation, and industrial pollution, have been the dominant drivers since the 19th century.

 

Wildlife extinction: The last generation of wild creatures

Across the planet, the wild voices of nature are falling silent. Forests that once echoed with birdsong now stand still, and grasslands that once trembled under herds of elephants and antelope are empty.

 

Humanity’s relentless expansion, deforestation, pollution, poaching, and climate change have pushed countless species to the brink of extinction. Scientists estimate that animals are disappearing at a rate 1,000 times faster than natural evolution would allow.

 

Every lost species is a broken thread in the web of life, weakening ecosystems that sustain us all. From the majestic tiger to the humble honeybee, wildlife is vanishing before our eyes. The tiger’s forests are shrinking, elephants are slaughtered for ivory, and coral reefs, home to a quarter of marine species, are dying from heat and acidification.

 

Even insects, the invisible engineers of our planet, are declining so rapidly that crops and pollination systems are at risk. This is not just a tragedy for nature; it is a warning for humanity. When the wild disappears, so does the balance that keeps our air clean, our soil fertile, and our climate stable.

 

Governments and individuals must act decisively. Nations need to strengthen conservation laws, expand protected areas, and enforce bans on illegal wildlife trade. Global cooperation is essential to preserve biodiversity hotspots in Africa, Asia, and South America.

 

At the same time, individuals can make a difference by supporting ethical tourism, reducing consumption of animal products linked to habitat loss, and amplifying awareness through education and social media.

 

Technology and science offer hope. Conservation drones monitor poaching zones, genetic research revives endangered species, and rewilding projects restore habitats where animals once thrived. However, these efforts require funding, political will, and public support. The survival of wildlife is not a luxury; it is a necessity for the planet’s health and our own.

 

We are the generation standing at the edge of history. If we fail to protect the wild now, future generations will inherit a world stripped of its beauty and balance. The last generation of wild creatures is watching us. Whether they vanish or endure depends on the choices we make today.

Earth on the edge: How human activity is rewriting the story of life

Human activity has become the most powerful force shaping the planet. From the depths of the oceans to the peaks of the mountains, the fingerprints of humanity are everywhere.

Forests are cleared for agriculture, rivers are dammed for power, and cities expand relentlessly into habitats once ruled by wildlife. The Earth, once balanced by natural rhythms, now struggles to adapt to the pace of human ambition.

Deforestation, pollution, and climate change have disrupted ecosystems that took millions of years to evolve. Species vanish faster than scientists can record them, and coral reefs, the rainforests of the sea, are bleaching into silence.

The air we breathe and the water we drink are increasingly burdened by industrial waste, plastic, and carbon emissions. Humanity’s progress has come at a cost that nature can no longer quietly absorb.

Yet, amid the destruction, there are stories of renewal. Re-wilding projects in Europe have brought wolves and bison back to landscapes where they disappeared centuries ago.

In Africa, community‑led conservation efforts protect elephants and lions while creating sustainable livelihoods. Across Asia and South America, forests are being replanted, and marine sanctuaries are giving endangered species a second chance.

These efforts remind us that the same hands that destroy can also heal. The challenge is not only scientific but moral. Every choice, what we eat, how we travel, what we consume, contributes to the planet’s future.

The story of life is being rewritten, and humanity must decide whether it will be remembered as the author of extinction or the guardian of renewal. The Earth is on the edge, but it is not beyond saving.

 

Environmental Hazards in Africa: The Growing Threat to People and Nature

Access to clean drinking water remains a problem in developing Africa.

Environmental problems are not only caused by improper use of nature’s resources but also by unreasonable exploitation, overpopulation of states, low incomes of the population, and unemployment, as the natural environment experiences degradation.

The state of the natural environment of African countries is reflected in the high rates of population reproduction, which are associated with the expansion of acreage and pastures, the growing number of cities, and the excessive and irrational use of natural resources.

The most acute environmental problems of Africa today are reduced soil fertility, accelerated erosion, deforestation, growing water scarcity, deteriorating surface water and air quality, cutting down evergreen forests, and disappearing plant and animal species.

Other causes of environmental problems are the poverty of states and the neglect of environmental consequences. Dirty industries and pollution affect African countries. Environmental degradation also affects food, farming, and livestock.

A typical example of an environmental problem in Africa is that of the Sahel, a vast natural area 400 km wide south of the Sahara from the Atlantic to Ethiopia. The Sahel is a transitional semi-desert zone from deserts to savannas.

The northern boundary of the Sahel is the isoline of the annual precipitation amount of 100–200 mm, and the southern boundary is 600 mm. The average temperature here is + 27 ... + 29 ° С. The humid summer period does not last long, and 80–90% of the precipitation evaporates.

The dry season lasts 8-10 months. The main type of economic activity over the centuries has been nomadic and semi-nomadic cattle breeding. During the wet season, cattle graze in the north of the Sahel, and in the dry season, it is distilled to the south.

This use of land led to a violation of the ecological balance in the twentieth century, which resulted in an increase in the area and the movement of deserts to the south, up to 10 km per year, desertification, and the transformation of arid lands into desert.

The main consequence of this process is an increase in the number of droughts. Some of them went down in history as the 'Sahel tragedy, from 1968 to 1974, and from 1984 to 1985. Africa has 17% of the world's forests. 

Spontaneous deforestation for firewood, valuable trees leads to a reduction of forests. Africa has lost 90% of its evergreen coastal rainforests. In Madagascar, for example, evergreen forests are preserved only in small areas in the east of the island.

A crucial problem in Africa is the shortage of freshwater. To solve it, scientists have proposed various watering projects, for example, in the Sahara. There are projects to divert the Congo River to the Sahara and the creation on the site of the ancient lakes of Chad, the Sahara, and Chad.

The presence of rapids on African rivers creates conditions for the irrigation of drylands through the construction of large reservoirs. Reservoirs Kariba on the Zambezi River, Nasser on the Nile River, are examples of the rational use of African surface water.

Poor waste disposal and pollution in Africa an opportunities to invite strange diseases from the developed world to Africa.

National Parks of African countries are taking steps to save wildlife. For these purposes, specially protected areas are created. At the beginning of the twentieth century, the first national parks appeared in Africa: Albert, Virunga, Serengeti, Rwenzori, etc.

After liberation from colonial oppression, 25 new national parks were created at once, and by the beginning of the XXI century, protected areas accounted for more than 7% of its territory. The first place in the number of national parks is Kenya (15% of the area).

The largest in the area is Tsavo National Park, more than 2 million hectares, where lions, rhinos, giraffes, Kafa buffaloes, and 450 bird species are protected. The park is best known for herding elephants. In South Africa, savannahs and South African fauna are protected.

Timber exports within parentheses in Africa generate large income for many African countries, yet Africa faces threatening challenges, such as deforestation.

Westerners come to the continent for quality wood, so the area of tropical forests has significantly decreased. African leaders must find solutions to save our continent because the continuous cutting down of trees will affect the population and the environment.
