Man-made definition is - manufactured, created, or constructed by human beings; specifically : synthetic. Plastics have many uses throughout society. Natural and Man-made Causes of Global Warming Global warming is the most common term that comes up when we talk about climate change or pollution. Examples of proxies include stable isotope measurements from ice cores, growth rates in tree rings, species composition of sub-fossil pollen in lake sediment or foraminifera in ocean sediments, temperature profiles of boreholes, and stable isotopes and mineralogy of corals and carbonate speleothems. by James Murphy Cost constraints often restrict surveys to sample only one or two countries from each continent or focus on only one region. Natural and man-made hazards. But in some parts of the world it is less than this and some more. Natural landscape: A natural landscape is one that is a result of the changes that have taken place naturally in the earth’s crust. Such changes sculpted and designed the landscape into mountains and valleys, and effect of weather over centuries further brought about gradual changes in a way that did not disturb the delicate ecological […] The JRC continually monitors and assesses the risk of disasters such as droughts, floods, forest fires, earthquakes, tsunamis, cyclones and dispersion of air pollutants.
