The concept of this article is totally new to me. Air travel contributes at least three percent of global greenhouse gases and it is still rising. However, it is really good to know that there are certain airlines begin to pay attention on this issue. Dutch airline nowdays has used recyceled cooking oil(biofuel) to power planes. In fact, the plane had a 50-50 mix of biofuel and regular jet fuel in one of its four engines, which help cut carbon emission making by the planes while also help reduce nagative impact on biodiversity and food supply. In a word, KLM airline really shows a model of "green airline".

The article addresses a big issue that we are currently facing worldwide, what to do with all the electronic waste? This Time article focuses on 20 different ways that can revert this situation and help to reuse some of the precious metals and parts for future electronic devices. Algae biofuel, thin-film solar power, smart meters, new electric cars, and rooftop wind power are just some of the examples the article shares on how green technologies are already being used to help us make the life on our planet to last longer. Extensive research has been done on many different areas and now it's just a matter of countries and companies to enforce such technologies, in order for us to preserve our natural resources.

This article briefly introduced some new ideas about transportation tools for green technologies developing in the tourism industry. Although discovering and implementing a new thought of recycling for environmental friendly is very difficult and expensive, the green activities are significant and need to be continual going on.

Considering the three R's--reduce, reuse and recycle--may be difficult in an industry that is known to change styles with every season. Kamilah Grace Cole, the founder of K. Grace, has always had a love for fashion and the environment. And she only uses sustainable, eco-friendly materials in its designs, everything from organic cotton to recycled hemp, silk, modal and buttons made from coconut shells. But the biggest challenge is still finding the right mix of textiles and materials. Compared to traditional materials Organic cotton starts with a non-genetically modified seed and there are no pesticides used, therefore the end product is safer and gentler. Hemp is considered a renewable source because it grows so quickly without pesticides and is a very durable and versatile fabric. Although it is a little bit expensive for the cost of the sustainable material, but all of us have such kind of the social responsibility to support fair wages, healthier farmers, cleaner water, air and a commitment to making the world a better place.
