(2) Earth is covered with 71% water, there is still shortage of usable water ​

Answer 1

⭐ Deforestation is responsible for increase in earth's temperature.

Ans.

We lose a crucial ally in keeping excess carbon out of the atmosphere (and in slowing global warming),

Even more emissions are created when felled trees release the carbon they’d been storing, and rot or burn on the forest floor, and

What most often replaces the now-vanished forest, livestock and crops, generate massive amounts of even more greenhouse gases. Taken together, these emissions account for a quarter of all emissions worldwide.

⭐ Earth is covered with 71% water, there is still shortage of usable water.

Ans.

The earth has an abundance of water, but unfortunately, only a small percentage (about 0.3 percent), is even usable by humans. The other 99.7 percent is in the oceans, soils, icecaps, and floating in the atmosphere. Still, much of the 0.3 percent that is useable is unattainable.
