Answer 1

we all know that our environment is very necessary for our healthy existence on the earth. A healthy environment depends on the good habits of human beings and the circumstances we create. Human, animal, plants, earth and environment are indirectly connected to each other and necessary for the existence of healthy life here.

However, by any means if our environment gets affected negatively, creates lots of problems and many challenges in living a simple and healthy life. Our environment acts as a natural world for us and provides a protection to us from the natural calamities. However, it becomes helpless in protecting us if we disturbs its natural cycle and force it to harm us.

Answer 2

Answer:

▪︎To qualify as a biodiversity hotspot, a region must meet two strict criteria:

1. It must have at least 1,500 vascular plants as endemics which is to say, it must have a high percentage of plant life found nowhere else on the planet.

2. It must have 30% or less of its original natural vegetation.

_____________________________________________

▪︎Around the world, 36 areas qualify as hotspots. They represent just 2.4% of Earth’s land surface, but they support more than half of the world’s plant species as endemics — i.e., species found no place else — and nearly 43% of bird, mammal, reptile and amphibian species as endemics.
