Major global issues Informally, a global issue describes any social, economic, political or environmental problems that affects the global community, possibly in a catastrophic way.
GLOBAL ISSUES INCLUDE: GLOBAL. PLANTATION. PLASTIC DISPOSAL. POLLUTION
PLANTATION Tree planting is the process of transplanting tree seedlings, generally forestry, land reclamation, or landscaping purpose. It differs from the transplantation of larger trees in arboriculture, and from the lower cost but slower and less reliable distribution of tree seeds. In silviculture the activity is known as reforestation, or afforestation depending on whether the area being planted has or has not recently been forested. It involves planting seedlings over an area of land where the forest has been harvested or damaged by fire, disease or human activity. Tree planting is carried out in many different parts of the world, and strategies may differ widely across nations and regions and among individual reforestation companies. Tree planting is grounded in forest science, and if performed properly can result in the successful regeneration of a deforested area. Reforestation is the commercial logging industry's answer to the large-scale destruction of old growth forests but a planted forest rarely replicates the biodiversity and complexity of a natural forest.

Planting tress can reduce the rate of pollution
Plastic disposal Most plastics are made from oil and most plastics do not biodegrade which makes it difficult to dispose off. There are no natural processes in place that can absorb non biodegradable plastic back into the biological cycle. It cannot be composted or left to rot where it is dropped or dumped like organic rubbish. Plastic lasts for decades, maybe centuries, possibly for ever. WHICH MEANS that every bit of plastic created has to be collected up and specially treated. All of these processes are time-consuming and so expensive.
AREAS WITH PLASTIC DISPOSAL AREAS WITH PLASTIC RECYCLED
RECYCLING PLASTIC CAN MAKE THE ENVIRONMENT CLEAN AND GREEN.
pollution Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of chemical substances or energy, such as noise, heat or light. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Pollution is often classed as point source or nonpoint source pollution. The burning of coal and wood, and the presence of many horses in concentrated areas made the cities the cesspools of pollution. The Industrial Revolution brought an infusion of untreated chemicals and wastes into local streams that served as the water supply.
