How are humans altering the environment?
The world population is increasing at a dramatic rate. It is expected to exceed 9 billion by 20501. Accompanying this growth has been increased consumption of natural resources essential for our way of life. As a result we face a number of environmental challenges including the destruction of natural habitats, air and water pollution and land . Many scientists believe these actions are causing climate change.
What is meant by environmental sustainability?
In order for our actions to be environmentally sustainable, they must satisfy the needs of today, whether it is the supply of food, water or energy, without compromising the future environment of our planet. This means we must consider the impact our actions may have on the planet’s ecosystems, biodiversity and climate, and how this may affect the environment for future generations.
Climate change and sustainability
Many scientists believe that the current level of global CO2 emissions is not environmentally sustainable and that it will cause considerable climate change if no action is taken to reduce these emissions.
In 2008, the International Energy Agency (IEA) released a report entitled “Energy Technology Perspectives” which stated that a combination of technologies is required to reduce CO2 emissions. In addition to recommending increased use of renewable energy sources, the IEA concluded that “CO2 capture and storage for power generation and industry is the most important single new technology for CO2 savings”2.
What is a carbon footprint?
Carbon footprints are the total amount of greenhouse emissions produced by an individual, organisation, or even an entire country, and are used to measure the impact our lives have on the environment. These are calculated to identify areas where emissions can be reduced and efficiency improved. Carbon footprints are also used for calculating the amount of required to become .
