ENVIRONMENTAL CHANGES – WE CAN MAKE A DIFFERENCE

EARTH’S ENVIRONMENT

The natural environment is the set of living and non-living things on Earth which occur in a state substaintially not Influenced by humans.It’s an environment that encompases the interaction of all living species.

BUT EARTH IS CHANGING RAPIDLY AS A RESULT OF HUMAN ACTIONS AND GETTING WORSE, NOT BETTER.

Why ?

Here comes the environmental changesClimate changeNutrient enrichmentToxin accumulationOzone depletionEmergence of diseasesThreat to BiodiversityNatural calamitiesOcean acidification

THE FACTORS FOR THIS CHANGE• Deforestation• Over Fishing• Industrialization• Pollution• Destroying the wildlifes• Greenhouse gases

In this mean time the most critical patient is Earth !

THREATS TO BIODIVERSITY

Biodiversity means Variety and Variability of Species

Ephemeral phenomenon

all forms of life, including all species and genetic variants within species

all ecosystems that contain and sustain those diverse forms of life.

Impact of climate change on bioviversity

Ability to find food

What do they eat?

Plants on the move!

2005

White spruce trees in the upper Savage River in Denali National Park, AK.

Geographic response to climate change

Species migrating into new areas as temperatures warm

WE CAN MAKE A DIFFERENCE

Community actions for impact reduction Control of forest fires Do not use slash & burn crop wastes.

Plaugh them back to land Restrict use of bioenergy & biofuels No permission for coal-based

industries after 2010 Use of clean energies like solar and

wind power for running industries and household lights.

Total ban on fuel woods (storage of wet carbon) for energy

Use incinerators for burning dead bodies

Capture of CO2 from air

RECYCLING IS THE BEST POLICY

Engineering for ChangeSafe environment Engineering issues give the hazardous environment first response and safety solutions.

Prototypes that are helping in recovering the threatening of this disordered
