Carbon dioxide is the main type of greenhouse gas emission, and carbon dioxide emission (i.e. carbon emission) is the average greenhouse gases emission of the production, trafficking, using and recycling of a certain product. All human activities emits carbon dioxides, but it can be reduced by decreasing industrial, enterprise carbon emission and pollution, and leading sustainable ways of lives. It would become the most important topic to be discussed in this century.

Meat production (e.g. cattle or lamb farming) causes a lot of environmental problems. Herbivores like cattle and lamb produces a lot of methane and carbon dioxide, which are greenhouse gases causing rise of temperature on Earth. Imported frozen meat would also increase carbon foodprint. Thus, eating less meat can help to reduce environmental problems caused by meat production.

Many of the resources on Earth can be used up one day. If we continue to consume resources unsustainably, some of the non-renewable resources would be consumed, and the environment would be severely damaged. There will be a chance that we will not be able to live on Earth anymore.

Organic farming could help to solve the problem of food crisis. The normal farming practices nowadays is a single cultivation method that peruses maximum yield, which is not able to fulfill the need of the world population. In the contrary, organic farming could increase the yield of diversified crops and protect the ecosystem. It can help increasing job opportunities, improving the living standard and infrastructure in the rural area, and increasing the competitiveness of the local farmers. This would be the way of environmental protection and sustainable development of our society in the future.

LOHAS is the short form of Lifestyles of Health and Sustainability, which is a healthy and sustainable way of lifestyle.

Sustainable consumption is a way of consumption that would improve our living standard, but would not cause any damages to the environment or sacrifice the need of natural resources for development of the future generation.

“Ecological Footprint”is the measurement of human need of natural resources. It measures everything we eat and use, like crops, meat, seafood, and even timber and wood we consume. “Ecological Footprint” is like a balanced bill, if we compare the total amount of resources of human consumption with the resources on Earth, we would estimate the status of human consumption.

Different resources are being consumed in human activities, such as agriculture, fisheries, building and industries. Currently, these resources can only support the lives of 2 billion people, however, the Earth needs 1.5 years to regenerate what we consume in one year. As a result, our needs exceed the regeneration rate of the Earth, which is called ecological overshooting.

We are utilizing bioresources in different aspects of our daily lives, such as the raw materials of our clothes and daily products, or the farm products as our food.

Bioresources are the organic part of the natural resources, which includes the economically valuable organisms and their communities in the biosphere.

Organic farming is a way of sustainable farming. It emphasizes on matching with the laws of Nature, use of non- GM and non – chemically processed methods, cultivating crops according to suitable seasons and environment. The advantages of organic farming includes production of natural and healthy foods for human, and conservation of soil quality and biodiversity in the soil.

It is to maintain the agricultural production quality and the income of farmers, and reduce the impacts of agriculture to the environment, and fulfill the need of food supplies and conserve natural resources at the same time. Therefore, sustainable agriculture and environmental protection is closely related.

“Sustainable agriculture” is a system of production of animals and plant. It is operated as to (1) provide the human need of food and dietary fiber, (2) increase the quality of environment and natural resources, (3) Use of non-renewable and agricultural resources in the most efficient way, (4) Keep the economic vitality in the farm, and (5) increase the living standards of farmers and even the whole society.
