IELTS Writing Task 2: Environment - Problem & Solution Sample Answer

Deforestation has accelerated to levels that scientists warn are approaching irreversible tipping points, particularly in tropical regions where forest ecosystems store vast quantities of carbon and support the majority of terrestrial biodiversity. Addressing this crisis requires confronting the specific economic forces that drive it.

Agricultural expansion is the dominant cause, accounting for approximately 80% of global deforestation. Demand for cattle ranching in Brazil's Amazon region, palm oil cultivation in Indonesia and Malaysia, and subsistence farming across sub-Saharan Africa all incentivise the conversion of forest to agricultural land. Commercial logging, often enabled by inadequate governance and corruption in countries with weak rule of law, clears vast areas of economically valuable timber, with roads opened for logging subsequently providing access for settlers and farmers. Infrastructure projects including dams, mines, and road construction complete the primary drivers. In each case, the immediate economic incentive to clear land substantially outweighs the diffuse, long-term costs of forest loss that are distributed globally.

Effective solutions must change these economic incentives. The REDD+ programme, under which developing countries receive payments for verified reductions in deforestation rates, has demonstrated measurable effectiveness in countries including Brazil, where the Amazon deforestation rate fell by over 80% between 2004 and 2012 following strong governance and financial incentives. Mandatory supply chain due diligence - requiring companies to verify that commodities such as soy, beef, and palm oil are deforestation-free - is increasingly implemented in the European Union and creates market incentives for sustainable land management. Strengthening indigenous land rights is additionally proven to reduce deforestation, as indigenous-managed territories consistently show lower rates than comparable areas under other governance regimes.

Deforestation is primarily an economic governance failure. It requires economic solutions: payments for ecosystem services, supply chain accountability, and strong property rights for forest communities.
