From the Ted Talk video “It’s our city. Lets fix it.” by Alessandra Orofino, I found that over half of the worlds population live in cities. This means that urban population is increasing which has many advantages as well as disadvantages.

Global problems such as climate change, the energy crisis and poverty are all factors which are caused by urbanisation. With mass global energy consumption and gas emissions occurring within our cities, urbanisation and overpopulation is the underlying problem. Building cities has caused good quality public spaces to generally disappear, which inhibits relations between people who live there.

However, increasing urbanisation allows for recreational activities, housing and better transport routes. When more people live in one specific area the government will put more money into this area, which increases job opportunities and prevents it from becoming run down. Cities allow human happiness to flourish.

Political process can help combat challenges faced by the urban environment in many ways. For example, moving to cleaner technologies such as electric cars which will help reduce the 80% of gas emissions from cars within cities. The preservation of natural resource areas and the protection of habitats and species will reduce environmental pressure.
