Human Expansion and Animal Habitats

The question
As cities and farmland expand, the natural habitats of many animals are being destroyed. What are the causes of this problem, and what measures could be taken to address it?

Band 9 model answer

Across the globe, forests, wetlands and grasslands are vanishing beneath expanding cities and farms, displacing the creatures that once inhabited them. This essay will examine the principal drivers of habitat loss before proposing practical measures to curb it.

The causes are rooted in relentless human demand. A swelling global population requires ever more housing, infrastructure and food, prompting the clearance of wilderness for suburbs, roads and crops. Economic incentives intensify the pressure, as logging, mining and large-scale agriculture promise short-term profit that habitats, with no market price, cannot defend. Weak planning regulations and the simple absence of long-term thinking allow this conversion to proceed largely unchecked, fragmenting once-continuous ecosystems into isolated pockets too small to sustain wildlife.

Several measures could meaningfully reverse the trend. Governments should designate and rigorously enforce protected reserves, while channelling new development into already-urbanised land to spare untouched terrain. Constructing wildlife corridors that reconnect fragmented habitats would allow animals to migrate and breed safely across human landscapes. Equally important is sustainable agriculture, which raises yields on existing fields and thereby removes the pretext for clearing further wilderness. Finally, educating citizens and offering financial incentives for conservation can align private interests with ecological survival.

In conclusion, habitat destruction stems chiefly from population growth and the pursuit of profit on land that nature cannot protect. Yet the problem is far from insoluble. Through strict protection, smarter urban planning, habitat corridors and sustainable farming, societies can accommodate human progress while leaving sufficient room for the animal kingdom to endure.
