Detailed explanation-1: -Land use change, pollution, poor water quality, chemical and waste contamination, climate change and other causes of ecosystem degradation all contribute to biodiversity loss and, can pose considerable threats to human health.

Detailed explanation-2: -In a two-way process, climate change is one of the main drivers of biodiversity loss, but destruction of ecosystems undermines nature’s ability to regulate greenhouse gas (GHG) emissions and protect against extreme weather, thus accelerating climate change and increasing vulnerability to it.

Detailed explanation-3: -When land is converted for agriculture, some animal and plant species may lose their habitat and face extinction. But climate change is playing an increasingly important role in the decline of biodiversity. Climate change has altered marine, terrestrial, and freshwater ecosystems around the world.

Detailed explanation-4: -Biodiversity, or the variety of all living things on our planet, has been declining at an alarming rate in recent years, mainly due to human activities, such as land use changes, pollution and climate change.

Detailed explanation-5: -The correct answer is b. If humans had not interfered with nature by building industrial societies, the global climate would not have changed significantly. The given statement is true as industrial gases have proved to be the most important factor associated with greenhouse gases.
