The Year 2075 is deemed as the "Year of Dryness" by the members of the United Nations
Environment Programme. Why do you think they have predicted this catastrophic event? What
can you do to stop such a thing from happening? Discuss and express your

plzz can anyone answer this!!!!​

The long-term good health of populations depends on the continued stability and

functioning of the biosphere’s ecological and physical systems, often referred to

as life-support systems. We ignore this long-established historical truth at our

peril: yet it is all too easy to overlook this dependency, particularly at a time

when the human species is becoming increasingly urbanized and distanced from

these natural systems. The world’s climate system is an integral part of this

complex of life-supporting processes, one of many large natural systems that are

now coming under pressure from the increasing weight of human numbers and

economic activities.

By inadvertently increasing the concentration of energy-trapping gases in the

lower atmosphere, human actions have begun to amplify Earth’s natural greenhouse effect. The primary challenge facing the world community is to achieve

sufficient reduction in greenhouse gas emissions so as to avoid dangerous interference in the climate system. National governments, via the UN Framework

Convention on Climate Change (UNFCC), are committed in principle to seeking

this outcome. In practice, it is proving difficult to find a politically acceptable

course of action—often because of apprehensions about possible short-term

economic consequences.

This volume seeks to describe the context and process of global climate change,

its actual or likely impacts on health, and how human societies should respond,

via both adaptation strategies to lessen impacts and collective action to reduce

greenhouse gas emissions. As shown later, much of the resultant risk to human

populations and the ecosystems upon which they depend comes from the projected extremely rapid rate of change in climatic conditions. Indeed, the prospect

of such change has stimulated a great deal of new scientific research over the

past decade, much of which is elucidating the complex ecological disturbances

that can impact on human well-being and health—as in the following example.

The US Global Change Research Program (Alaska Regional Assessment Group)

recently documented how the various effects of climate change on aquatic

ecosystems can interact and ripple through trophic levels in unpredictable ways.

For example, warming in the Arctic region has reduced the amount of sea ice,

impairing survival rates for walrus and seal pups that spend part of their life cycle

on the ice. With fewer seal pups, sea otters have become the alternative food

source for whales. Sea otters feed on sea urchins, and with fewer sea otters sea
