This is How Jamaica is helping to heal the ozone layer

The ozone, a region of atmosphere 10 to 50 kilometres above the earth’s surface, contains a protective shield that absorbs ultraviolet radiation. Without this barrier, the powerful sun will damage human DNA, cause burns and skin cancer, disrupt the climate and trigger environmental, social and economic tsunamis. By 1993, Jamaica, like most countries on earth, took action by acceding to the Vienna Convention for the Protection of the Ozone Layer and its Montreal Protocol on Substances that deplete the Ozone Layer. Since 2012 the United Nations Development Programme (UNDP) has been supporting the Government to meet its international obligations under the Protocol to phase out harmful ozone depleting gases — primarily targeting industries that manufacture ozone-depleting gases, or that import them for use in the refrigeration and air conditioning sector.

Google and the web tracking pages explained

Chief policy officer Johnny Ryan used Google’s Chrome browser to conduct his research. He had no logins, cookies or browsing history on the device so was, in effect, a new user.
He said he discovered hidden webpages that had a unique address. It acted as an identifier, which was unique to him. This so-called pseudonymous marker, when combined with cookies, can help track user activity across the web, he claims. Cookies – small pieces of code that are embedded in websites and downloaded to devices to track how users browse the net – require permissions from the user to be used, which the hidden webpage does not.
Over the course of just one hour of web browsing, he said, Google created at least nine of these pages and 11 duplicate pages that transferred data about him.
That data was not seen by him but could have included information about age and gender, habits, social media usage, ethnicity or political affiliation, he said.
Eight companies other than Google were active on one or more of these pages and the identifiers for him were used 278 times, he found.
