Thank you for inviting me to join your list. Your article on arsenic and bacteria is interesting and intriguing: human intervention in such complex cases raises hope but also invites to be aware of possible retroaction effects, don't you think?
Nice to hear from you again. Thanks for responding to my invitation. I am following the energy developments in your area as ourselves in this part of the world have been caught off guard. The failure to take appropriate action on time has led to a serious build up to an energy crisis situation. Talk to you about that in due course.
