Green technology is also known as sustainable technology. It is environment friendly technology. In the future green technology should be used as a key tool in the transition from climate change. A sustainable technological revolution will create a brighter future. Eco-friendly technology trends help us prepare for future opportunities, possibilities and challenges just as technology trends inform us about the future and climate change.

Green technology is the best way to combat the effects of climate change and pollution. Earth has a finite amount of natural resources. Now present most of those natural resources have already been depleted or destroyed. The life of the world is endangered due to climate change, increase in global temperature, increase in the number and impact of natural disasters. Therefore various eco-friendly technologies are needed to keep the earth habitable. It is possible to get rid of this crisis by increasing the use of various environmentally friendly renewable energy sources.

Our planet's climate is constantly changing rapidly. These include increasingly severe droughts, increasing depletion of groundwater reserves, ocean acidification, rising sea levels, rapid spread of diseases, and extinction of macroparasites and species. Natural disasters, environmental hazards are an extreme crisis in the present world. Nature's hostile behavior towards humans is very painful. Because this natural calamity takes away everyone from the child to the old man. Due to various human activities, excessive use of fossil fuels, destruction of forests, etc., the habitable earth is gradually deteriorating.

So there is no alternative to green technology to sustain the existence of life on earth. One of the best-known examples of green technology is the solar cell. Which converts energy from natural light directly into electrical energy through the photovoltaic process. Many countries in the developed world are already increasing their use of environmentally friendly renewable energy. Electricity generation using solar and wind energy has reduced the use of fossil fuels in many countries. In addition many countries in the developed world have set an example by using wind turbines or wind speed to generate electricity.

The main goal of green technology is to protect the environment. Another important goal is to reverse the damage done in the past and conserve natural resources. This new advancement in eco-friendly green technology helps solve plastic pollution, food waste, deforestation and environmental issues. Along with environment friendly green technology it is possible to make green economy very easily. A green economy is an economy that ensures human development but at the same time reduces environmental risks and eliminates scarcity. So that economic development without harming the natural balance and environment is green economy. Ignoring the natural environment a developed prosperous society, economy, beautiful life cannot be thought of.

A beautiful favorable environment is one of the prerequisites for development. If the climate and natural environment are threatened then the economy will also be threatened. In view of which all the countries of the world are now emphasizing on ecological balance and favorable natural environment for economic development and overall prosperity. In the past most of the countries of the world did not have much awareness about this.

But due to the impact of global industrialization and the development of urban civilization then the imbalance in the climate and natural environment has caused a terrible disaster. Now almost all countries in the world are taking remedial measures in this regard. The concept of green economy has gained wide popularity worldwide since the natural environment is under threat due to climate change. It is difficult to protect the environment without the promotion of green industries. For this reason the whole world is now turning towards green investment and sustainable economic business. Otherwise the earth will become uninhabitable for humans in the near future.

We already have enough damage to this environment. Due to the changes in the world's climate, on the one hand, the severity of winter is increasing, on the other hand, the people of the world are suffering from instability due to unbearable heat. Along with identifying the materials that cause environmental damage, environment-friendly technologies should be used instead of these materials. The use of green technology should be increased to save the environment. Green fence should be built. Nowadays green technology is widely used in various fields.

Smart grids, electric vehicles and advanced recycling technologies have become popular in various regions around the world. Technologies for renewable energy sources have become more advanced and affordable. As a result the environment has started to have a positive impact in various countries around the world. Eco-friendly technology does not destroy natural resources. Rather it finds ways to extract natural resources from the environment technically. The biggest advantage of green technology is that it can be reused.

This green technology is used in various fields. In addition to providing environmental protection, green technology reduces atmospheric pollution, helps reduce the effects of global warming and ensures the protection of natural resources. Development of green technologies provides opportunities for new job creation and helps in economic growth. Also technology can reduce energy wastage. Which leads to long-term economic success worldwide.

The initial cost of introducing green technologies is usually high which is often a barrier. Some green technologies still face technical problems and lack of functionality. They need further development. If we overcome all these problems and use environmentally friendly technology for the welfare of biodiversity, it will be a special blessing for the entire world including mankind and animals. The future of green technology is bright and promising.

It opens up new horizons in energy management, renewable energy use, health technology, urban development and climate change. Advances in technology and new innovations will make the future of this sector more advanced and productive. These advances in technology will help make our world safer and more sustainable.
