Today, climate changes are undoubtedly leaving a strong impact on human life and it is usually associated with large scale phenomenon. Due to climate change global food security threat is create and it is one of the most important challenges in the 21st century. Continuous increase in population in the stressed environment is raising a strong question how to supply sufficient food? Assessment of WHO stated that 60% of the world population depends on traditional medicines which are basically obtained from plants. Anthropogenic activities plays important role and contributing towards climate changes around the world
Climate change can change the quality of natural product and it effects the taste and medicinal value of some Arctic plants. Although it was reported that such changes could either be positive or negative. Production of secondary metabolites is increased in stressed conditions; however production of secondary metabolites is influenced by many factors such as competition between the plants, light, soil and humidity etc.
Plants matter!!!
According to recent study published in Journal Nature Climate Change, Climate change could lead to the globally widespread loss of plants occurred around the world. This study collected data of 50,000 common species plants as well as animals. They concluded that more than half of the plants would get affected till 2080 due to continuous rise in greenhouse gas emissions.
Plants are dependent on certain factor such as temperature, light, carbon dioxide (CO2), rainfall and moisture to produce the crop products which are essential for human nutrition as well as health. The amount of these factors varies between locations. Crop management is therefore a huge challenge because it is always highly dependent on climate and environmental factors.
Crop production also provides the food, fodder and fiber for clothes. Continuous increases in population create plenty of burdens on earth and this is the one of the major factor affecting climate. Climate change has pronounced effect on biogeography, temperature, rainfall, soil and herbivory.
