Climate change is the critical issue of our time and now is the essential moment to do something about it. It is believed by the researchers that, there is still time to tackle and overcome climate transformation, but it will entail an extraordinary effort from all divisions of society. Global climate transformation has already had evident effects on the atmosphere. Impacts that researchers had foreseen in the past would result from global climate change are now taking place: loss of sea ice, faster sea level rise and elongated, more strong heat waves
Global warming, the phenomenon of growing typical air temperatures close to the surface of Earth over the past one to two centuries. It is a foremost aspect of recent climate change and has been confirmed by direct temperature measurements and by observations of several effects of the heating. Environment researchers have collected comprehensive observations of various weather phenomena (such as temperatures, rainfall, and storms) and of connected influences on weather (such as ocean tides and the environment’s chemical composition). The data acquired indicate that Earth’s climate has altered over almost every imaginable timescale since the origin of geologic time and that the effect of human actions since the commencement of the Industrial Revolution
Green energy derives from natural sources such as sunlight, airstream, rain, waves, plants and geothermal heat. While green energy resources are renewable, which means they're certainly replenished, on the other hand, fossil fuels are a limited resource that take millions of years to develop and will continue to reduce with utilization. Moreover, Renewable energy sources have a much lesser influence on the atmosphere than fossil fuels, which are producing toxins such as greenhouse gases as a by-product, contributing to climate modification.
Global warming and climate change caused by pollution damage humans health, wildlife, and our environment. Global warming, also recognized interchangeably as climate change, is instigated by a blanket of pollution that traps heat around the earth. This contaminant comes from motor vehicles, industries, domestic activities, and power plants that burn fossil fuels such as oil, coal, natural gas, and gasoline. Global warming pollution distinguishes no boundaries. It enters the atmosphere, distributes across the globe, and traps heat around the earth for more than 100 years after it is released. That is why we need to reduce global warming pollution now, because will still feel the effects of global warming for years to come.
Recycling refers to converting an element into raw materials which can be used again, generally for a entirely new product. Even though it is an energy consuming procedure, it conserves natural resources such as timber, water and minerals. Reusing means using an item as it is without treatment. This lessens contamination and debris, thus making it a more sustainable procedure. Many researchers is of the opinion that Reusing is better than recycling for the reason that it saves the energy it takes to dismantle and re-manufacture products. It also expressively decreases waste and pollution by means of reducing the necessity for raw materials, saving both forests and water supplies.
Natural hazards are naturally happening physical events caused by events which can be geophysical, hydrological, climatological, meteorological or biological such as earthquakes, landslides, tsunamis, volcanic activity, avalanches and floods, drought and wildfires, disease epidemics. Man-made hazards are events that are caused by humans and occur in or close to inhabited settlements. This consist of environmental degradation, pollution and accidents. Climate change and unplanned urbanization are the major aggravating aspects which will lead to increased occurrence, complexity and severity of disasters.
Environmental toxicology is an interdisciplinary field of science concentrating on the investigation of the detrimental impacts of various chemical, biological, and physical agents on living organisms in the ecosystems, including humans. It occupies an imperative niche among toxicology, ecological health, and public policy. Ecotoxicology is the learning of the effects of toxic chemicals on biological organisms, especially at the population and ecosystem. It is a multidisciplinary arena, which assimilates toxicology and ecology.
Geoscience is the technical learning of the planet Earth and its various natural geologic schemes. In a progressively globalized world, with a swiftly increasing population, earth science has an vital role to perform in building resilience societies to withstand natural hazards and climate change.
Circular Economy often refers to as an economic system intended at eliminating debris and the recurrent use of resources. Circular systems retain reuse, allotment, repair, restoration, remanufacturing and recycling to generate a closed-loop system, decreasing the use of resource inputs and the generation of waste, contamination and carbon emissions. This phenomenon not only deliver the benefits such as reducing burden on the environment, enhancing the safety of the supply of raw materials but also plays a major role in boosting the competitiveness, motivating innovation, advancing economic growth, creating jobs
Climate change has the capacity to greatly damage the food availability and accessibility, and even affect food quality. Factors such as anticipated upsurges in temperatures, changes in precipitation patterns, deviations in extreme weather events, and reductions in water availability may lead to reduced agricultural productivity. These impacts threaten our health by affecting the food and water we consume.
The observation of earth's different phenomenon like earthquakes, soil study, ocean life study, climate behaviour, and many other phenomenons that is responsible for our survival. The physical aspect of earth is monitored and observed to predict and take measures on how to prevent any damage. For example in Japan, it is a country where earthquakes and tsunami are persistent, so the scientists have developed houses made from wood, and the shores are planted with observatories that monitor the water level 24/7 and whenever there is any unusual behavioural they warn the people to clear out the chore and go to places far from sea and ocean at a safe place.
