Question

In a process known as deforestation, humans cut down millions of trees every year to build houses, generate energy, and make paper products. Which of the following describes the most likely effect of deforestation on the natural world? A. Animals that live in trees will start living in the ocean instead, resulting in overpopulation of the ocean. B. Millions of animals will lose their natural habitats, resulting in the extinction of many species. C. The natural world will benefit because cutting down trees helps reduce air pollution. D. Humans will eventually run out of trees to cut down and instead will start using brick to build homes.

Answer 1

Forests still cover about 30 percent of the world’s land area, but they are disappearing at an alarming rate. Between 1990 and 2016, the world lost 502,000 square miles (1.3 million square kilometers) of forest, according to the World Bank—an area larger than South Africa. Since humans started cutting down forests, 46 percent of trees have been felled, according to a 2015 study in the journal Nature. About 17 percent of the Amazonian rainforest has been destroyed over the past 50 years, and losses recently have been on the rise.

We need trees for a variety of reasons, not least of which is that they absorb not only the carbon dioxide that we exhale, but also the heat-trapping greenhouse gases that human activities emit. As those gases enter the atmosphere, global warming increases, a trend scientists now prefer to call climate change. Tropical tree cover alone can provide 23 percent of the climate mitigation needed over the next decade to meet goals set in the Paris Agreement in 2015, according to one estimate.

Answer 2

B is the only logical answer

the problem with A is evolution doesn't happen that fast and the species adapted for the trees aren't suited for the water

the problem with C is that trees help cut down on air pollution so that statement is just wrong

the problem with D is that it's just stupid don't pick D
