Answer 1

Answer:

At current rates of deforestation, rainforests will vanish altogether in a century. Stopping climate change will remain an elusive goal unless poor nations are helped to preserve them

If you want to see the world’s climate changing, fly over a tropical country. Thirty years ago, a wide belt of rainforest circled the earth, covering much of Latin America, south-east Asia and Africa. Today, it is being rapidly replaced by great swathes of palm oil trees and rubber plantations, land cleared for cattle grazing, soya farming, expanding cities, dams and logging.

People have been deforesting the tropics for thousands of years for timber and farming, but now, nothing less than the physical transformation of the Earth is taking place. Every year about 18m hectares of forest – an area the size of England and Wales – is felled. In just 40 years, possibly 1bn hectares, the equivalent of Europe, has gone. Half the world’s rainforests have been razed in a century, and the latest satellite analysis shows that in the last 15 years new hotspots have emerged from Cambodia to Liberia. At current rates, they will vanish altogether in 100 years.

About 12% of all man-made climate emissions now comes from deforestation, mostly in tropical areas

As fast as the trees go, the chance of slowing or reversing climate change becomes slimmer. Tropical deforestation causes carbon dioxide, the main greenhouse gas, to linger in the atmosphere and trap solar radiation. This raises temperatures and leads to climate change: deforestation in Latin America, Asia and Africa can affect rainfall and weather everywhere from the US Midwest, to Europe and China.

The consensus of the world’s atmospheric scientists is that about 12% of all man-made climate emissions – nearly as much as the world’s 1.2bn cars and lorries – now comes from deforestation, mostly in tropical areas. Conserving forests is critical; the carbon locked up in Democratic Republic of the Congo’s 150m hectares of forests are nearly three times the world’s global annual emissions.

And as the forests come down, the people who live in or around them and depend on them become impoverished. Without the forests, people migrate to cities, or move to richer countries in search of work. The world’s rainforests not only provide food, energy security, incomes and medicinal plants for 300 million people, but are home to the richest wildlife in the world.
